Besides the usual house Mouse, there is the wood Mouse, which forms a magazine of grain and nuts underground for winter store; and the harvest Mouse, which builds a little round nest between the stalks of corn. The Squirrel is also of this order. This pretty little creature lives in the trees, chiefly feeding upon nuts; can leap well, and run up the branches of trees with surprising agility. The Flying Squirrel has a broad expansion of skin between the fore and hind legs on each side, so that when stretched out, they form a sort of parachute; this enables the creature to leap to a great distance from tree to tree, and supports it in the air as it goes. The Porcupine (Hystrix cristata), so celebrated for its quills, which supply a sort of defensive armour, is of this order. * * * * * [Illustration: FIG. 62. ANTEATER (Myrmecophaga jubata).] 4. The EDENTATA, or Anteaters, have no teeth, but a peculiarly shaped tongue, which is covered with viscid mucus, and which they project and retract with great rapidity, causing the Ants and Termites, on which they feed, to adhere to it, and be carried into their mouths. The Great Anteater (Myrmecophaga jubata, fig. 62) is a very extraordinary animal in appearance; it has an enormously prolonged nose, and the back is covered with a sort of mane; the tail, also, is of prodigious size, and very bushy; when this curious animal lies down to sleep, the long snout is thrust under it, and the tail laid across the back, the end of the snout projecting behind. In this position, it would lead anyone to suppose that the head was where the tail really is, and that when looking at the creature's hinder part, they were looking at its head; and the sudden reversal of the position of these parts, when it gets up quickly, is certainly extremely ridiculous. * * * * *
